You might want to correct that typo
offering up to a massive 16GB utilizing sixteen SandForce SF-2581 controllers
Otherwise: very nice work! Although enterprise storage is not really my personal interest right now.

And...much of this technology will filter down into client drives, so we have that to look forward to.
As to a Hadoop test, we're currently planning out next generation tests and will definitely consider something of this nature.

Plus does this card have TRIM support. I have read that TRIM is disabled under RAID 0.

My question, however, has nothing to do with that.
So, to the article author, can you give more flavor to the issue of durability and compare/contrast the durability of this device compared to the FusionIO Drive2 Duo card? Do you think 100k rewrites, 1e6, etc.? How many years under fairly heavy use, 3, 5, or 7? Those are very different numbers, 5 could work if the money were available and people knew the limitations before purchase, 7 would be awesome, but 3 gives serious pause...

Now in terms of other factors, the Z-Drive R4 is a stripe of 8 individual drives with individual NAND pools. The design of a FIO ioDrive or ioDrive2 for example uses a single controller with a large pool of NAND. You can have more parts fail over time in the FIO setting, since there are more redundant pieces of NAND for a given capacity to failover to as the drive ages. In the R4 setting, with smaller individual pools you have fewer pieces to failover to before the drive fails.
